www.shorewall.net and ftp.shorewall.net is currently down. Until it is back

up, a small server with very limited bandwidth is being used temporarly. You

will likely experience better response time from the <a

for the inconvenience.<br /> <br /> <h2>Introduction to Shorewall</h2>
|
||||
<h3>This is the Shorewall 1.4 Web Site</h3> The information on this site
|
||||
applies only to 1.4.x releases of Shorewall. For older versions:<br />

|

- the packet filter facility built into the 2.2 Linux kernels. Also the name
|

of the utility program used to configure and control that facility.
|
||||
Netfilter can be used in ipchains compatibility mode.</li><li>iptables - the
|
||||
utility program used to configure and control Netfilter. The term

'iptables' is often used to refer to the combination of

iptables+Netfilter (with Netfilter not in ipchains compatibility mode).</li></ul>
|
||||
<h3>What is Shorewall?</h3> The Shoreline Firewall, more commonly known as
|
||||
"Shorewall", is high-level tool for configuring Netfilter. You
|
||||
describe your firewall/gateway requirements using entries in a set of
|
||||
configuration files. Shorewall reads those configuration files and with the
|
||||
help of the iptables utility, Shorewall configures Netfilter to match your
|
||||
requirements. Shorewall can be used on a dedicated firewall system, a
|
||||
multi-function gateway/router/server or on a standalone GNU/Linux system.
|
||||
Shorewall does not use Netfilter's ipchains compatibility mode and can
|
||||
thus take advantage of Netfilter's connection state tracking
|
||||
capabilities.<br /> <br /> Shorewall is <span
|
||||
style="text-decoration: underline;">not</span> a daemon. Once Shorewall has
|
||||
configured Netfilter, it's job is complete although the <a
|
||||
href="starting_and_stopping_shorewall.htm">/sbin/shorewall program can be
|
||||
used at any time to monitor the Netfilter firewall</a>.<br /> <h3>Getting

|
||||
</div> <p>Problems Corrected since version 1.4.8:</p> <ol><li>There has been
|
||||
a low continuing level of confusion over the terms "Source NAT"
|
||||
(SNAT) and "Static NAT". To avoid future confusion, all instances of
|
||||
"Static NAT" have been replaced with "One-to-one NAT" in the
|
||||
documentation and configuration files.</li><li>The description of NEWNOTSYN
|
||||
in shorewall.conf has been reworded for clarity.</li><li>Wild-card rules
|
||||
(those involving "all" as SOURCE or DEST) will no longer produce an
|
||||
error if they attempt to add a rule that would override a NONE policy. The
|
||||
logic for expanding these wild-card rules now simply skips those
|
||||
(SOURCE,DEST) pairs that have a NONE policy.</li></ol> <p>Migration Issues:<br />
|
||||
    None.<br /> <br /> New Features: </p> <ol><li>To
|
||||
cut down on the number of "Why are these ports closed rather than
|
||||
stealthed?" questions, the SMB-related rules in
|
||||
/etc/shorewall/common.def have been changed from 'reject' to
|
||||
'DROP'.</li><li>For easier identification, packets logged under the
|
||||
'norfc1918' interface option are now logged out of chains named
|
||||
'rfc1918'. Previously, such packets were logged under chains named
|
||||
'logdrop'.</li><li>Distributors and developers seem to be regularly
|
||||
inventing new naming conventions for kernel modules. To avoid the need to
|
||||
change Shorewall code for each new convention, the MODULE_SUFFIX option has
|
||||
been added to shorewall.conf. MODULE_SUFFIX may be set to the suffix for
|
||||
module names in your particular distribution. If MODULE_SUFFIX is not set in
|
||||
shorewall.conf, Shorewall will use the list "o gz ko o.gz".<br />
|
||||
<br /> To see what suffix is used by your distribution:<br /> <br /> ls
|
||||
/lib/modules/$(uname -r)/kernel/net/ipv4/netfilter<br /> <br /> All of the
|
||||
files listed should have the same suffix (extension). Set MODULE_SUFFIX to
|
||||
that suffix.<br /> <br /> Examples:<br /> <br />
|
||||
     If all files end in ".kzo" then set
|
||||
MODULE_SUFFIX="kzo"<br />      If all
|
||||
files end in ".kz.o" then set MODULE_SUFFIX="kz.o"</li><li>Support
|
||||
for user defined rule ACTIONS has been implemented through two new files:<br />
|
||||
<br /> /etc/shorewall/actions - used to list the user-defined ACTIONS.<br />
|
||||
/etc/shorewall/action.template - For each user defined <action>,
|
||||
copy this file to /etc/shorewall/action.<action> and add the
|
||||
appropriate rules for that <action>. Once an <action> has
|
||||
been defined, it may be used like any of the builtin ACTIONS (ACCEPT, DROP,
|
||||
etc.) in /etc/shorewall/rules.<br /> <br /> Example: You want an action that
|
||||
logs a packet at the 'info' level and accepts the connection.<br />
|
||||
<br /> In /etc/shorewall/actions, you would add:<br /> <br />
|
||||
     LogAndAccept<br /> <br /> You would then
|
||||
copy /etc/shorewall/action.template to /etc/shorewall/LogAndAccept and in
|
||||
that file, you would add the two rules:<br />
|
||||
        LOG:info<br />
|
||||
        ACCEPT<br />
|
||||
<br /></li></ol> <p><b>12/03/2003 - Support Torch Passed</b> <b><img

|
||||
Effective today, I am reducing my participation in the day-to-day support of
|
||||
Shorewall. As part of this shift to community-based Shorewall support a new
|
||||
<a href="https://lists.shorewall.net/mailman/listinfo/shorewall-newbies">Shorewall
|
||||
Newbies mailing list</a> has been established to field questions and
|
||||
problems from new users. I will not monitor that list personally. I will
|
||||
continue my active development of Shorewall and will be available via the
|
||||
development list to handle development issues -- Tom. <p><b>11/07/2003 -

Shorewall 1.4.8</b><b><br /> <br /> </b> Problems Corrected since version
|
||||
1.4.7:<br /> </p> <ol><li>Tuomo Soini has supplied a correction to a problem
|
||||
that occurs using some versions of 'ash'. The symptom is that
|
||||
"shorewall start" fails with:<br />  <br />   
|
||||
local: --limit: bad variable name<br />    iptables v1.2.8:
|
||||
Couldn't load match `-j':/lib/iptables/libipt_-j.so:<br />
|
||||
   cannot open shared object file: No such file or directory<br />
|
||||
   Try `iptables -h' or 'iptables --help' for more
|
||||
information.</li><li>Andres Zhoglo has supplied a correction that avoids
|
||||
trying to use the multiport match iptables facility on ICMP rules.<br />
|
||||
 <br />    Example of rule that previously caused
|
||||
"shorewall start" to fail:<br />  <br />
|
||||
          
|
||||
ACCEPT      loc  $FW 
|
||||
icmp    0,8,11,12<br /> <br /></li><li>Previously, if
|
||||
the following error message was issued, Shorewall was left in an
|
||||
inconsistent state.<br />  <br />    Error: Unable to
|
||||
determine the routes through interface xxx<br /> <br /></li><li>Handling of
|
||||
the LOGUNCLEAN option in shorewall.conf has been corrected.</li><li>In
|
||||
Shorewall 1.4.2, an optimization was added. This optimization involved
|
||||
creating a chain named "<zone>_frwd" for most zones defined
|
||||
using the /etc/shorewall/hosts file. It has since been discovered that in
|
||||
many cases these new chains contain redundant rules and that the
|
||||
"optimization" turns out to be less than optimal. The implementation
|
||||
has now been corrected.</li><li>When the MARK value in a tcrules entry is
|
||||
followed by ":F" or ":P", the ":F" or ":P"
|
||||
was previously only applied to the first Netfilter rule generated by the
|
||||
entry. It is now applied to all entries.</li><li>An incorrect comment
|
||||
concerning Debian's use of the SUBSYSLOCK option has been removed from
|
||||
shorewall.conf.</li><li>Previously, neither the 'routefilter'
|
||||
interface option nor the ROUTE_FILTER parameter were working properly. This
|
||||
has been corrected (thanks to Eric Bowles for his analysis and patch). The
|
||||
definition of the ROUTE_FILTER option has changed however. Previously,
|
||||
ROUTE_FILTER=Yes was documented as enabling route filtering on all
|
||||
interfaces (which didn't work). Beginning with this release, setting
|
||||
ROUTE_FILTER=Yes will enable route filtering of all interfaces brought up
|
||||
while Shorewall is started. As a consequence, ROUTE_FILTER=Yes can coexist
|
||||
with the use of the 'routefilter' option in the interfaces file.</li><li>If
|
||||
MAC verification was enabled on an interface with a /32 address and a
|
||||
broadcast address then an error would occur during startup.</li><li>he NONE
|
||||
policy's intended use is to suppress the generating of rules that
|
||||
can't possibly be traversed. This means that a policy of NONE is
|
||||
inappropriate where the source or destination zone is $FW or "all".
|
||||
Shorewall now generates an error message if such a policy is given in
|
||||
/etc/shorewall/policy. Previously such a policy caused "shorewall
|
||||
start" to fail.</li><li>The 'routeback' option was broken for
|
||||
wildcard interfaces (e.g., "tun+"). This has been corrected so that
|
||||
'routeback' now works as expected in this case.<br /></li></ol>
|
||||
Migration Issues:<br /> <ol><li>The definition of the ROUTE_FILTER option in
|
||||
shorewall.conf has changed as described in item 8) above.<br /></li></ol>
|
||||
New Features:<br /> <ol><li>A new QUEUE action has been introduced for
|
||||
rules. QUEUE allows you to pass connection requests to a user-space filter
|
||||
such as ftwall (http://p2pwall.sourceforge.net). The ftwall program allows
|
||||
for effective filtering of p2p applications such as Kazaa. For example, to
|
||||
use ftwall to filter P2P clients in the 'loc' zone, you would add
|
||||
the following rules:<br /> <br />    QUEUE  
|
||||
loc        
|
||||
net    tcp<br />    QUEUE  
|
||||
loc        
|
||||
net    udp<br />    QUEUE  
|
||||
loc        
|
||||
fw     udp<br /> <br /> You would normally want
|
||||
to place those three rules BEFORE any ACCEPT rules for loc->net udp or
|
||||
tcp.<br /> <br /> Note: When the protocol specified is TCP ("tcp",
|
||||
"TCP" or "6"), Shorewall will only pass connection requests
|
||||
(SYN packets) to user space. This is for compatibility with ftwall.</li><li>A
|
||||
BLACKLISTNEWNONLY option has been added to shorewall.conf. When this option
|
||||
is set to "Yes", the blacklists (dynamic and static) are only
|
||||
consulted for new connection requests. When set to "No" (the default
|
||||
if the variable is not set), the blacklists are consulted on every packet.<br />
|
||||
<br /> Setting this option to "No" allows blacklisting to stop
|
||||
existing connections from a newly blacklisted host but is more expensive in
|
||||
terms of packet processing time. This is especially true if the blacklists
|
||||
contain a large number of entries.</li><li>Chain names used in the
|
||||
/etc/shorewall/accounting file may now begin with a digit ([0-9]) and may
|
||||
contain embedded dashes ("-").</li></ol> <p><b>10/26/2003 -

<h2>Introduction to Shorewall</h2>
|
||||
<h3>This is the Shorewall 1.4 Web Site</h3>
|
||||
The information on this site applies only to 1.4.x releases of
|
||||
Shorewall. For older versions:<br>
|
||||
<ul>
|
||||
<li>The 1.3 site is <a href="http://www.shorewall.net/1.3"
|
||||
target="_top">here.</a></li>
|
||||
<li>The 1.2 site is <a href="http://shorewall.net/1.2/"
|
||||
target="_top">here</a>.</li>
|
||||
</ul>
|
||||
<h3>Glossary</h3>
|
||||
<ul>
|
||||
<li><a href="http://www.netfilter.org">Netfilter</a> - the
|
||||
packet filter facility built into the 2.4 and later Linux kernels.</li>
|
||||
<li>ipchains - the packet filter facility built into the 2.2
|
||||
Linux kernels. Also the name of the utility program used to configure
|
||||
and control that facility. Netfilter can be used in ipchains
|
||||
compatibility mode.</li>
|
||||
<li>iptables - the utility program used to configure and
|
||||
control Netfilter. The term 'iptables' is often used to refer to the
|
||||
combination of iptables+Netfilter (with Netfilter not in ipchains
|
||||
compatibility mode).</li>
|
||||
</ul>
|
||||
<h3>What is Shorewall?</h3>
|
||||
The Shoreline Firewall, more commonly known as "Shorewall", is
|
||||
high-level tool for configuring Netfilter. You describe your
|
||||
firewall/gateway requirements using entries in a set of configuration
|
||||
files. Shorewall reads those configuration files and with the help of
|
||||
the iptables utility, Shorewall configures Netfilter to match your
|
||||
requirements. Shorewall can be used on a dedicated firewall system, a
|
||||
multi-function gateway/router/server or on a standalone GNU/Linux
|
||||
system. Shorewall does not use Netfilter's ipchains compatibility mode
|
||||
and can thus take advantage of Netfilter's connection state tracking
|
||||
capabilities.<br>
|
||||
<br>
|
||||
Shorewall is <span style="text-decoration: underline;">not</span> a
|
||||
daemon. Once Shorewall has configured Netfilter, it's job is complete
|
||||
although the <a href="starting_and_stopping_shorewall.htm">/sbin/shorewall
|
||||
program can be used at any time to monitor the Netfilter firewall</a>.<br>

||||

</div>
|
||||
<p>Problems Corrected since version 1.4.8:</p>
|
||||
<ol>
|
||||
<li>There has been a low continuing level of confusion over the
|
||||
terms "Source NAT" (SNAT) and "Static NAT". To avoid future confusion,
|
||||
all instances of "Static NAT" have been replaced with "One-to-one NAT"
|
||||
in the documentation and configuration files.</li>
|
||||
<li>The description of NEWNOTSYN in shorewall.conf has been
|
||||
reworded for clarity.</li>
|
||||
<li>Wild-card rules (those involving "all" as SOURCE or DEST)
|
||||
will no longer produce an error if they attempt to add a rule that
|
||||
would override a NONE policy. The logic for expanding these wild-card
|
||||
rules now simply skips those (SOURCE,DEST) pairs that have a NONE
|
||||
policy.</li>
|
||||
</ol>
|
||||
<p>Migration Issues:<br>
|
||||
None.<br>
|
||||
<br>
|
||||
New Features: </p>
|
||||
<ol>
|
||||
<li>To cut down on the number of "Why are these ports closed
|
||||
rather than stealthed?" questions, the SMB-related rules in
|
||||
/etc/shorewall/common.def have been changed from 'reject' to 'DROP'.</li>
|
||||
<li>For easier identification, packets logged under the
|
||||
'norfc1918' interface option are now logged out of chains named
|
||||
'rfc1918'. Previously, such packets were logged under chains named
|
||||
'logdrop'.</li>
|
||||
<li>Distributors and developers seem to be regularly inventing
|
||||
new naming conventions for kernel modules. To avoid the need to change
|
||||
Shorewall code for each new convention, the MODULE_SUFFIX option has
|
||||
been added to shorewall.conf. MODULE_SUFFIX may be set to the suffix
|
||||
for module names in your particular distribution. If MODULE_SUFFIX is
|
||||
not set in shorewall.conf, Shorewall will use the list "o gz ko o.gz".<br>
|
||||
<br>
|
||||
To see what suffix is used by your distribution:<br>
|
||||
<br>
|
||||
ls /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter<br>
|
||||
<br>
|
||||
All of the files listed should have the same suffix (extension). Set
|
||||
MODULE_SUFFIX to that suffix.<br>
|
||||
<br>
|
||||
Examples:<br>
|
||||
<br>
|
||||
If all files end in ".kzo" then set
|
||||
MODULE_SUFFIX="kzo"<br>
|
||||
If all files end in ".kz.o" then set
|
||||
MODULE_SUFFIX="kz.o"</li>
|
||||
<li>Support for user defined rule ACTIONS has been implemented
|
||||
through two new files:<br>
|
||||
<br>
|
||||
/etc/shorewall/actions - used to list the user-defined ACTIONS.<br>
|
||||
/etc/shorewall/action.template - For each user defined <action>,
|
||||
copy this file to /etc/shorewall/action.<action> and add the
|
||||
appropriate rules for that <action>. Once an <action> has
|
||||
been defined, it may be used like any of the builtin ACTIONS (ACCEPT,
|
||||
DROP, etc.) in /etc/shorewall/rules.<br>
|
||||
<br>
|
||||
Example: You want an action that logs a packet at the 'info' level and
|
||||
accepts the connection.<br>
|
||||
<br>
|
||||
In /etc/shorewall/actions, you would add:<br>
|
||||
<br>
|
||||
LogAndAccept<br>
|
||||
<br>
|
||||
You would then copy /etc/shorewall/action.template to
|
||||
/etc/shorewall/LogAndAccept and in that file, you would add the two
|
||||
rules:<br>
|
||||
LOG:info<br>
|
||||
ACCEPT<br>
|
||||
<br>
|
||||
</li>

||||
</p>
|
||||
<ol>
|
||||
<li>Tuomo Soini has supplied a correction to a problem that
|
||||
occurs using some versions of 'ash'. The symptom is that "shorewall
|
||||
start" fails with:<br>
|
||||
<br>
|
||||
local: --limit: bad variable name<br>
|

|
||||
Try `iptables -h' or 'iptables --help' for more
|
||||
information.</li>
|
||||
<li>Andres Zhoglo has supplied a correction that avoids trying
|
||||
to use the multiport match iptables facility on ICMP rules.<br>
|
||||
<br>
|
||||
Example of rule that previously caused "shorewall start"
|
||||
to fail:<br>
|
||||
<br>
|
||||
|
||||
ACCEPT loc $FW
|
||||
icmp 0,8,11,12<br>
|
||||
<br>
|
||||
</li>
|
||||
<li>Previously, if the following error message was issued,
|
||||
Shorewall was left in an inconsistent state.<br>
|
||||
<br>
|
||||
Error: Unable to determine the routes through interface xxx<br>
|
||||
<br>
|
||||
</li>
|
||||
<li>Handling of the LOGUNCLEAN option in shorewall.conf has
|
||||
been corrected.</li>
|
||||
<li>In Shorewall 1.4.2, an optimization was added. This
|
||||
optimization involved creating a chain named "<zone>_frwd" for
|
||||
most zones defined using the /etc/shorewall/hosts file. It has since
|
||||
been discovered that in many cases these new chains contain redundant
|
||||
rules and that the "optimization" turns out to be less than optimal.
|
||||
The implementation has now been corrected.</li>
|
||||
<li>When the MARK value in a tcrules entry is followed by ":F"
|
||||
or ":P", the ":F" or ":P" was previously only applied to the first
|
||||
Netfilter rule generated by the entry. It is now applied to all entries.</li>
|
||||
<li>An incorrect comment concerning Debian's use of the
|
||||
SUBSYSLOCK option has been removed from shorewall.conf.</li>
|
||||
<li>Previously, neither the 'routefilter' interface option nor
|
||||
the ROUTE_FILTER parameter were working properly. This has been
|
||||
corrected (thanks to Eric Bowles for his analysis and patch). The
|
||||
definition of the ROUTE_FILTER option has changed however. Previously,
|
||||
ROUTE_FILTER=Yes was documented as enabling route filtering on all
|
||||
interfaces (which didn't work). Beginning with this release, setting
|
||||
ROUTE_FILTER=Yes will enable route filtering of all interfaces brought
|
||||
up while Shorewall is started. As a consequence, ROUTE_FILTER=Yes can
|
||||
coexist with the use of the 'routefilter' option in the interfaces file.</li>
|
||||
<li>If MAC verification was enabled on an interface with a /32
|
||||
address and a broadcast address then an error would occur during
|
||||
startup.</li>
|
||||
<li>he NONE policy's intended use is to suppress the generating
|
||||
of rules that can't possibly be traversed. This means that a policy of
|
||||
NONE is inappropriate where the source or destination zone is $FW or
|
||||
"all". Shorewall now generates an error message if such a policy is
|
||||
given in /etc/shorewall/policy. Previously such a policy caused
|
||||
"shorewall start" to fail.</li>
|
||||
<li>The 'routeback' option was broken for wildcard interfaces
|
||||
(e.g., "tun+"). This has been corrected so that 'routeback' now works
|
||||
as expected in this case.<br>
|
||||
</li>
|
||||
</ol>
|
||||
Migration Issues:<br>
|
||||
<ol>
|
||||
<li>The definition of the ROUTE_FILTER option in shorewall.conf
|
||||
has changed as described in item 8) above.<br>
|
||||
</li>
|
||||
</ol>
|
||||
New Features:<br>
|
||||
<ol>
|
||||
<li>A new QUEUE action has been introduced for rules. QUEUE
|
||||
allows you to pass connection requests to a user-space filter such as
|
||||
ftwall (http://p2pwall.sourceforge.net). The ftwall program allows for
|
||||
effective filtering of p2p applications such as Kazaa. For example, to
|
||||
use ftwall to filter P2P clients in the 'loc' zone, you would add the
|
||||
following rules:<br>
|
||||
<br>
|
||||
QUEUE loc
|
||||
net tcp<br>
|
||||
QUEUE loc
|
||||
net udp<br>
|
||||
QUEUE loc
|
||||
fw udp<br>
|
||||
<br>
|
||||
You would normally want to place those three rules BEFORE any ACCEPT
|
||||
rules for loc->net udp or tcp.<br>
|
||||
<br>
|
||||
Note: When the protocol specified is TCP ("tcp", "TCP" or "6"),
|
||||
Shorewall will only pass connection requests (SYN packets) to user
|
||||
space. This is for compatibility with ftwall.</li>
|
||||
<li>A BLACKLISTNEWNONLY option has been added to
|
||||
shorewall.conf. When this option is set to "Yes", the blacklists
|
||||
(dynamic and static) are only consulted for new connection requests.
|
||||
When set to "No" (the default if the variable is not set), the
|
||||
blacklists are consulted on every packet.<br>
|
||||
<br>
|
||||
Setting this option to "No" allows blacklisting to stop existing
|
||||
connections from a newly blacklisted host but is more expensive in
|
||||
terms of packet processing time. This is especially true if the
|
||||
blacklists contain a large number of entries.</li>
|
||||
<li>Chain names used in the /etc/shorewall/accounting file may
|
||||
now begin with a digit ([0-9]) and may contain embedded dashes ("-").</li>

optimization involved creating a chain named "<zone>_frwd" for

most zones defined using the /etc/shorewall/hosts file. It has since

been discovered that in many cases these new chains contain redundant

Shorewall code for each new convention, the MODULE_SUFFIX option

suffix for module names in your particular distribution. If

<li>A new QUEUE action has been introduced for rules. QUEUE
|
||||
allows
|
||||
you to pass connection requests to a user-space filter such as
|
||||
ftwall (http://p2pwall.sourceforge.net). The ftwall program allows
|
||||
for effective filtering of p2p applications such as Kazaa. For
|
||||
example, to use ftwall to filter P2P clients in the 'loc' zone, you
|
||||
would add the following rules:<br>
|
||||
<br>
|
||||
<br>
|
||||
QUEUE loc
|
||||
net tcp<br>
|
||||
QUEUE loc
|
||||
net udp<br>
|
||||
QUEUE loc
|
||||
fw udp<br>
|
||||
<br>
|
||||
<br>
|
||||
You would normally want to place those three rules BEFORE any
|
||||
ACCEPT rules for loc->net udp or tcp.<br>
|
||||
<br>
|
||||
<br>
|
||||
Note: When the protocol specified is TCP ("tcp", "TCP" or "6"),
|
||||
Shorewall will only pass connection requests (SYN packets) to user
|
||||
space. This is for compatibility with ftwall.</li>

|

<li>A BLACKLISTNEWNONLY option has been added to
|
||||
shorewall.conf.
|
||||
When this option is set to "Yes", the blacklists (dynamic and
|
||||
static) are only consulted for new connection requests. When set to
|
||||
"No" (the default if the variable is not set), the blacklists are
|
||||
consulted on every packet.<br>
|
||||
<br>
|
||||
<br>
|
||||
Setting this option to "No" allows blacklisting to stop existing
|
||||
connections from a newly blacklisted host but is more expensive in
|
||||
terms of packet processing time. This is especially true if the
|
||||
blacklists contain a large number of entries.</li>
